Settlement day surprises. The 5 late discoveries that cost the most.

The period between contract exchange and settlement is typically 6 weeks. In that time, your conveyancer continues investigating the title and adjacent matters. Most settlements complete without incident. But the surprises that do emerge in this window can be devastating because the contract is already signed and the deposit is at risk.

This post is the five most expensive late-stage discoveries, in order of frequency.

Surprise 1: undisclosed building work without approvals

The most common late-stage surprise. The vendor or a previous owner completed building work (an extension, a deck, a granny flat, a pool, a substantial internal renovation) without obtaining the required council approvals.

How it surfaces: your conveyancer or building inspector identifies a discrepancy between the property as it physically exists and the council's records.

The cost: council can require demolition or retrospective approval. Retrospective approval typically requires:

• Application fees and assessment fees
• Engineering certification that the work meets current standards (often it does not, because standards have changed since the work was done)
• Remedial work to bring the structure up to current standards (insulation, fire safety, structural reinforcement)

Total cost: $15,000-80,000 depending on the scale of the work. Some unauthorised structures must be demolished entirely.

How to avoid: comprehensive building inspection by a qualified inspector who can cross-reference the property against council records. Cost: $600-1,500. The inspection is often included in standard pre-purchase due diligence; if you skipped it, this surprise is the consequence.

Surprise 2: unregistered easement or unknown encumbrance

A drainage easement, a covenant, or another encumbrance that was not disclosed in the section 32 (VIC) or section 10.7 certificate (NSW) and was missed in the title search.

How it surfaces: the conveyancer's final title search before settlement reveals an encumbrance that was not on the earlier search, or council provides updated information that surfaces something previously hidden.

The cost: depends on what the encumbrance prevents. A drainage easement under your planned extension footprint is a $30-70k design problem. A restrictive covenant that prevents your planned use is the price of starting over.

How to avoid: comprehensive title search at multiple stages (pre-offer, exchange, settlement). Most conveyancers do this. If your conveyancer is doing only a single search, ask for additional.

Surprise 3: vendor financial distress affecting settlement

The vendor's financial situation changes between exchange and settlement. They cannot release the property (a creditor has placed a caveat, the bank has moved to repossess, family law proceedings have constrained the title).

How it surfaces: a few days before settlement, a caveat appears on the title or the vendor's bank moves to take possession.

The cost: settlement may be delayed weeks or months. In some cases, the deposit is at risk. In others, the buyer may be unable to settle at all and must rescind.

How to avoid: harder than the other surprises. The vendor's financial position is typically not disclosed. Some warning signs:

• The vendor's solicitor is the same as the vendor's main creditor's solicitor
• The vendor is selling significantly below market for no obvious reason
• The vendor refuses to grant short delay extensions when reasonable

Building a relationship with the vendor's conveyancer during the settlement period can sometimes surface concerns early.

Surprise 4: undisclosed building defects

The pre-purchase building and pest inspection missed a substantial defect that becomes obvious closer to settlement (or after settlement). Examples include:

• Termite damage in structural timbers (sometimes only visible from inside walls)
• Rising damp behind cabinetry
• Asbestos in materials the inspector did not investigate
• Foundation movement issues that show up after recent rainfall
• Roof leaks that only manifest in heavy rain

The cost: $10,000-100,000+ depending on the defect.

How to avoid: a thorough pre-purchase building and pest inspection from a qualified inspector with explicit instructions to investigate areas of concern. A standard inspection costs $400-700. A thorough inspection with extensive cavity-wall investigation costs $1,200-2,500.

For older properties (pre-1970), specifically request asbestos identification.

Surprise 5: rates and outgoings beyond expectations

Council rates, water rates, strata levies, body corporate special assessments, land tax, all are adjusted at settlement. Some have been higher than expected:

• A pending strata special assessment for major building works ($10,000-50,000 per unit)
• An unpaid land tax debt from previous years
• Council rate arrears
• Outstanding owners corporation levies

How it surfaces: the conveyancer's adjustments statement (typically prepared 1-2 weeks before settlement) shows the buyer's share of unpaid or upcoming obligations.

The cost: $5,000-50,000 depending on what is outstanding.

How to avoid: comprehensive review of the section 32 (VIC) or vendor's statement (other states), specifically including:

• Strata report (for strata-titled properties): $300-500. Reveals upcoming assessments and the body corporate financial position.
• Council rates certificate: $50-150. Reveals any outstanding rates.
• Land tax search: $100-200. Reveals any land tax debts attached to the property.

These are routine pre-settlement checks but some buyers skip them to save the few hundred dollars in fees.

What to do if a surprise arrives

Three pathways depending on the surprise:

Pathway 1: rescind under cooling-off (if available)

In states with cooling-off periods (5 days NSW, 3 days VIC, 5 days QLD, etc.), surprises discovered within the cooling-off window allow rescission with a small penalty.

After cooling-off, rescission requires either a contract condition (e.g. subject to finance, subject to building and pest) being unmet, or proof of misrepresentation by the vendor.

Pathway 2: negotiate compensation or repair before settlement

For surprises that are real but not deal-breakers (a defect that costs $15k to repair, an encumbrance that complicates but does not prevent your intended use), negotiating a price reduction at settlement is often achievable.

The vendor's incentive to negotiate is the cost to them of not settling: relisting, marketing, holding cost. A reduction of the surprise's repair cost often makes commercial sense for both sides.

Pathway 3: settle and pursue compensation post-settlement

For surprises that are clearly the vendor's fault (e.g. concealment of known defects, misrepresentation about authorised building work), settlement followed by legal action against the vendor can recover damages.

This is slow, expensive, and uncertain. Better to avoid the surprise than to recover from it.

How to maximise pre-exchange certainty

Three habits:

Habit 1: spend on inspection

The combination of a thorough building inspection, pest inspection, and (where applicable) strata report typically costs $1,200-2,500. This is one of the highest-value spends in the entire purchase process.

Habit 2: use a good conveyancer

A good conveyancer charges $1,500-3,000 for a residential conveyance. A cheap online conveyancer at $500 may save you $1,500 but skip the depth that prevents the surprises above.

Habit 3: read your own contract

Most buyers do not read the contract themselves. A 90-minute read with the conveyancer's notes alongside catches questions you would not otherwise ask. The questions catch the issues you would otherwise discover at settlement.

Settlement-day surprises are mostly preventable. The 6-week settlement window exists for a reason: to allow late-stage checks. Using the window for thorough checks rather than just paperwork is the difference between a clean settlement and a story you tell at dinner parties for years.
